Verbena plant named &#39; sunvivabura &#39;

ABSTRACT

Disclosed herein is a Verbena plant which has erect growth habit and good plant height. The plant has plentiful flowers in a spike, and great profusion of blooms. The blooming period is late April to November and flowering duration is long. The whole bush remains in bloom for a considerable period of time. The flower size is large and the petal color of the flowers is light purplish pink without eye. The plant is highly tolerant to heat and cold, and has high resistances to pests and diseases, particularly powdery mildew, and high resistance to rain.

BACKGROUND OF THE VARIETY

[0001] The present invention relates to a new and distinct variety of verbena plant obtained from crossing a Verbena hybrida ‘NOVARIS Rosepink with eye’ (♀) and a wild type of verbena plant Verbena peruviana (♂) native to Brazil.

[0002] Verbena is a very popular plant and is used for flower bedding and potting in the summer season. There are only a few varieties of Verbena plants which have abundant branching, many flowers in a spike, a long flowering duration and which have a high resistance to rain, heat, cold, and disease. Accordingly, this invention was aimed at obtaining a new variety having a erect growth habit, strong branching, many flowers in a spike, large diameter flowers, a high tolerance to heat and cold, and resistances to diseases and pests, and also having a light purplish pink color petal.

[0003] The new variety of Verbena plant according to this invention originated from crossing a Verbena hybrida ‘NOVARIS Rosepink with eye’ (♀) and a wild type of verbena plant Verbena peruviana VBD (♂) native to Brazil.

[0004] First of all, 33 seedling were obtained in the autumn of 1992, from crossing ‘NOVARIS Rosepink with eye’ as female parent and a wild type of verbena plant VBD (Verbena peruviana f. rosea) as pollen parent in the May of 1992. From this crossing, 8 seedlings were selected in view of erect growth habit and petal color, and propagated by cutting, and then grown as a trial by flower bedding and planter from the spring of 1993 to the autumn of 1994. Finally one plant was selected from these 8 seedlings. The botanical characteristics of the selected one seedling was examined, using parent varieties and similar varieties ‘NOVARIS Rosepink with eye’ and a wild type of verbena plant Verbena peruviana VBD for comparison. As a result, it was concluded that this Verbena is distinguishable from any other variety whose existence is known to us, and to uniform and stable in its characteristics. This new variety of Verbena plant was named ‘Sunvivabura’.

[0005] In the following description, the color-coding is in accordance with The Horticultural Color Chart of The Royal Horticultural Society, London, England (R.H.S. Color Chart), and the Inter-Society Color Council-Nation Bureau of Standards Color Name (I.S.C.C.-N.B.S. Color Name). A color chart based on The Japan Color Standard for Horticultural Plant (J.H.S. Color Chart) is also added for reference.
